A reduction in gonadal activity has also been observed; hibernation does not occur when the gonads are in an actively functional state. Perpetuation of the species requires that the animal be warm and active during the mating and pregnancy periods. There appears to be a relationship between sleep...
Researchers are also trying to determine how toharnessthe power of hibernation to help humans. They believe that it could be key to addressing health conditions like heart disease, and Alzheimer’s. Furthermore, hibernation’s ability to slow aging, which was observed in bats, could benefit spac...
A subset of genes in the current study were found previously to be DE in a microarray study in black bears (Ursus americanus)22, with the discrepancies possibly reflecting subtle species differences. That analysis identified 319 genes in liver that were DE. Of the 319 genes, 285 had a direct...
In the injection of electron-Bernstein waves (EBW) into a plasma, proposed for plasma heating and current drive in over-dense plasma, conversion of the fundamental to its second harmonic is predicted analytically and observed in computations. The mechanism is traced to the existence of locations ...
be verified via the master file table (seeChapter 4). Further, if there were six Restore Points, and the system file was not backed up in the older five Restore Points, and was only available in the most recent Restore Point, this would also provide an indication that the observed ...
We monitored all hamsters until trapping and observation failure in autumn, indicating immergence into the hibernaculum, and defined the date when the individual was trapped or observed for the last time during the pre-hibernation period as immergence date. To confirm that an individual terminated...
At arousal, these enzymatic activities reappear progressively in the splenic parenchyma. As soon as the normal temperature is reached, ferric granulations can again be observed in the red pulp; the acid and alkaline phosphatase activities are slightly more pronounced in the splenic parenchyma than ...
they observed an overall increase in ATP consumption in the hibernating states. Due to smaller animals undergoing larger temperature fluctuations during hibernation, the team conducted another Mant-ATP chase assay in colder temperatures, revealing that ATP consumption increased in the IBA and active s...
. Decreases in respiratory rate and oxygen consumption are observed during feigned death in the opossum35. During constriction by snakes, rats show reductions in body temperature and heart rate before dying due to inhibited respiration36. If prey animals can respond to constriction by reducing oxygen...
No apparent differences were observed in any behavioural tests. c, Results of the rotarod test. d, Results of the other tests. Box plots show the distribution of each group in specific tests; all elements of the box plots are as defined in Extended Data Fig. 5. e, Histology of tissues ...
